Description

Humidifying device using porous tiles {HUMIDIFICATION DEVICE USING POROUS TILES}

The present invention relates to a humidifying device using a porous tile.

Humidity indicates the amount of water vapor contained in the air, and low humidity occurs in dry climates or heated indoor spaces, adversely affecting health and generating static electricity, which causes many industrial problems.

A humidifier is a device for controlling indoor humidity, and can increase indoor humidity by using the humidifier, but an excessive increase in humidity may cause the growth of insects or mold.

Therefore, the humidifier must be able to control and maintain an appropriate indoor humidity and uniformly provide moisture over a wide range.

Humidification methods include a natural humidification method and a method of artificially humidifying by applying external energy to a device.

Methods using the device include a heating method, an ultrasonic method, and a vaporization method. The heating type humidifier has a high-temperature sterilization effect, but has disadvantages of high energy consumption and high noise. Ultrasonic humidification devices have fast humidification performance, but the size of water droplets is relatively large, about 5 μm, and thus there is a risk of bacterial propagation. In addition, the evaporation-type humidifier has the advantage of preventing the spread of germs and harmful substances, but has the disadvantage of making a lot of noise like the heating-type humidifier. In particular, these humidifiers have a disadvantage that the replacement cycle of the water tank is very short.

On the other hand, the natural humidification method has many advantages compared to the above-described humidification device because the size of water droplets is small, the humidification range is wide, and moisture is evenly distributed in the room. However, the natural humidification method has lower humidification efficiency compared to the case of using a humidifier, and in the case of using a towel using a capillary phenomenon that is commonly used, the inconvenience of having to frequently change towels, etc., as in the case of using a humidifier follow

Therefore, like the natural humidification method, the humidification range is wide and the moisture is evenly distributed in the room, but there is no problem of noise generation or bacterial propagation, and the humidification ability is excellent like the method using a humidifier, and additional work can be minimized. The development of a humidification method is required.

Hereinafter, a humidifying device 10 using a porous tile according to a first embodiment of the present invention will be described.

FIG. 1 is a cross-sectional view of the water supply unit, FIG. 5 is a perspective view of the water drainage unit of FIG. 1, and FIG. 6 is a view showing the moving direction of water flowing through the porous tile of FIG.

1 to 6, the humidifying device 10 using a porous tile according to the first embodiment of the present invention includes a porous tile 100, a water storage unit 200, a pipe 300, a water supply unit ( 400), a water drainage unit 500, a control unit 600 and a sensor unit 700 may be included.

The humidifying device 10 using porous tiles may supply water to the front surface of the porous tiles 100 arranged on the wall to adjust the humidity of the internal space. The humidifying device 10 using a porous tile may hold water inside the pores 120 in a high-humidity environment and release water inside the pores 120 in a low-humidity environment. That is, humidity can be controlled using a natural evaporation humidification method using the porous tile 100 capable of absorbing and releasing moisture according to the surrounding environment.

Since the humidifying device 10 using a porous tile only needs to flow water through the porous tile 100, it can be operated with less power than conventional humidifying devices and can produce a humidifying effect with low noise.

The humidifying device 10 using a porous tile supplies water to the front surface of the porous tile 100 in contact with the surrounding environment, and absorbs and releases water faster than when water is supplied to the rear surface. Thus, it can respond to the changing humidity of the surrounding environment.

Here, those skilled in the art related to this embodiment that other general-purpose components other than the components shown in FIGS. 1 to 6 may be further included in the humidifying device 10 using a porous tile When you grow up, you will understand.

The porous tile 100 may include a tile 110 and pores 120 . The porous tile 100 is continuously arranged on the wall surface and may include pores 120 . The porous tile 100 is a thin rectangular tile and may be disposed over a large area at regular intervals to cover a wall surface.

At least one porous tile 100 may be disposed along the direction of gravity. For example, the porous tile 100 may be arranged in four layers along the direction of gravity (see FIG. 1).

The porous tile 100 has a metabolism with the surrounding environment, such as absorbing and releasing water, and may be made of natural earth components harmless to the human body. For example, the porous tile 100 may include at least one selected from the group consisting of clay, white clay, loess, and combinations thereof. However, the shape and material of the porous tile 100 are not limited thereto and may have various shapes and materials.

The porous tile 100 may further include inorganic particles or metal oxides for controlling the particle size and pores 120 . The porous tile 100 includes a main material and a binder that function to absorb moisture and release moisture, and may additionally include additives. Gamma alumina, feldspar, diatomaceous earth, etc. may be included as the main material, glass frit powder, crushed glass powder, etc. may be used as the binder, and photocatalysts, opacifiers, etc. that activate TVOC decomposition may be used as the additives. .

The porous tile 100 is a tile including pores 120 and may have excellent hygroscopicity for absorbing moisture. The porous tile 100 may be highly utilized as a tile by maintaining a certain level of mechanical strength.

In the porous tile 100, the average size of pores 120 may be 5 μm or less. When the average size of the pores 120 of the porous tile 100 exceeds 5 μm, although the porous tile 100 absorbs and releases water, evaporation of moisture may occur slowly. In this case, it may be different from the purpose of the present invention to use as a humidifying device. Accordingly, the porous tile 100 may have micropores 120 having an average size of 5 μm or less and several nanometers.

The porous tile 100 may have an absorption rate of 25% or more. When the water absorption rate of the porous tile 100 is less than 25%, it cannot absorb a large amount of water for a short time. Accordingly, in the humidifying device 10 of the present invention, in which water is supplied from the top of the porous tile 100 and the water gradually moves to the porous tile 100 at the bottom by gravity, the amount of water flowing down without being absorbed is There can be many.

In addition, when the water absorption rate of the porous tile 100 is 25% or more, the maximum amount of moisture that the porous tile 100 can absorb can be increased. Accordingly, sufficient moisture can be supplied to the inner space of the room, which is the target of the present invention. Therefore, the porous tile 100 is manufactured to have a water absorption of 25% or more, thereby minimizing the amount of water supplied and at the same time securing a sufficient humidifying effect. Preferably, the water absorption rate of the porous tile 100 may be 30% or more.

The porous tile 100 may have a specific surface area of 10 m ² /g or more. When the specific surface area of the porous tile 100 is less than 10 m ² /g, moisture release efficiency may be reduced due to the small surface area. Accordingly, the specific surface area of the porous tile 100 may be 10 m ² /g or more. Preferably, it may be 20 m ² /g or more.

The porous tile 100 may have a porosity of 25 to 35%. The porosity of the porous tile 100 is a numerical value representing the degree of voids in pores, and refers to the percentage of the volume of pores relative to the total volume. The porosity can be calculated using a porosity measuring principle using mercury penetration using a capillary phenomenon in which liquid penetrates into fine pores.

When the porosity of the porous tile 100 is less than 25%, since the ratio of pores 120 is small, it cannot contain moisture to maintain appropriate humidity in the surrounding environment. In addition, the pores 120 may serve as passages for gases such as harmful gases, and the porosity of the porous tile 100 may be 25% or more for absorption of moisture and smooth circulation of gases.

When the porosity of the porous tile 100 exceeds 35%, the strength of the porous tile 100 to maintain a constant shape for a long period of time may be reduced due to the volume of too many pores 120 . In addition, it may be difficult to maintain a certain level of molding strength for processing the porous tile 100 . Therefore, the porosity of the porous tile 100 may be preferably 25 to 35%.

The porous tile 100 may have a thickness T1 of 5 mm to 10 mm. When the thickness T1 of the porous tile 100 is less than 5 mm, due to the characteristics of the porous tile 100 in which pores are formed, a certain level of mechanical strength may not be maintained and there may be concerns about damage during construction. In addition, since the absolute area of the pores 120 decreases, the amount of moisture absorption and release of the porous tile 100 decreases, so that a sufficient moisture control effect may not be obtained.

When the thickness T1 of the porous tile 100 exceeds 10 mm, the porous tile 100 protrudes excessively from a wall surface on which it is arranged, which may adversely affect utilization of internal space. Since water is supplied only to the front surface of the porous tile 100, even if the thickness T1 of the porous tile 100 exceeds 10 mm, it may not penetrate the rear surface of the porous tile 100 until moisture evaporates. Accordingly, even if the thickness T1 of the porous tile 100 exceeds 10 mm, the positive effect on the amount of moisture absorption and release may be insignificant.

In addition, as the thickness (T1) of the porous tile 100 increases more than necessary, the self-load of the porous tile 100 also increases, which may cause difficulties in construction and may affect durability due to the load caused by continuous gravity. can Accordingly, the porous tile 100 may have a thickness T1 of 6 to 10 mm.

The pores 120 may be pores that are evenly distributed over the entire surface of the porous tile 100 . The pores 120 may store external moisture inside or release internal water to the outside according to the surrounding environment (see FIG. 2 ). When the humidity is high, the pores 120 may absorb moisture through the pores 120 to lower the indoor humidity. When the humidity is low, the pores 120 release moisture stored in the pores 120 to increase indoor humidity. The pores 120 may be formed in a size of several nanometers and arranged in countless numbers to increase the specific surface area of the porous tile 100 .

The water storage unit 200 may include a water tank 210 and a motor 220 . The water storage unit 200 may store water supplied to the porous tile 100 .

The water tank 210 may be a container in which water is stored. The water tank 210 may have a box shape with an internal space formed to temporarily accommodate water supplied to the porous tile 100 .

The motor 220 may be coupled to the water tank 210 to provide power for supplying water. The motor 220 may supply water accommodated in the water tank 210 to the water supply unit 400 and deliver water drained from the water drainage unit 500 to the water tank 210 . Accordingly, water may be circulated in the water tank 210 , the water supply unit 400 , and the water drainage unit 500 by the motor 220 . The motor 220 may operate according to a control signal from the controller 600 to be described later.

The pipe 300 may include a supply pipe 310 and a drain pipe 320 . The pipe 300 may be a pipe or hose that is a path through which water moves by connecting the water storage unit 200 , the water supply unit 400 , and the water drainage unit 500 . However, the configuration of the pipe 300 is not limited thereto, and any configuration that connects the water storage unit 200, the water supply unit 400, and the water drainage unit 500 and allows water to move may be possible.

The supply pipe 310 may be a pipe or hose connecting the water storage unit 200 and the water supply unit 400 (see FIG. 1 ). The drain pipe 320 may be a pipe or hose connecting the water storage unit 200 and the water drainage unit 500 . However, the supply pipe 310 and the drain pipe 320 are merely exemplary connection methods of the pipe 300, and the pipe 300 is a single pipe, and the water storage unit 200, the water supply unit 400, and the water drainage It may have various methods such as connecting the unit 500 .

The water supply unit 400 may include a supply pipe 410 , a distribution pipe 420 and a spray nozzle 430 . The water supply unit 400 is connected to the water storage unit 200 and is positioned on top of the porous tile 100 to supply water to the entire surface of the porous tile 100 . The water supply unit 400 may supply water to the inside of the pores 120 of the porous tile 100 by flowing water from the top of the porous tile 100 to the entire surface of the porous tile 100 .

The water supply unit 400 may supply water to the porous tile 100 in various ways. For example, the water supply unit 400 is configured as a spray bar capable of spraying or configured to flow fine water droplets through a hole (not shown), so that water can be supplied without directly contacting the porous tile 100. .

The supply pipe 410 may be a pipe connected to the water storage unit 200 and extending in one direction on top of the porous tile 100 . The supply pipe 410 may serve as a passage through which water stored in the water storage unit 200 is moved to an upper portion of the porous tile 100 . The length and shape of the supply pipe 410 may vary depending on the required spray range of water, the arrangement and width of the porous tile 100, and the like. At this time, the supply pipe 410 may be made of SUS or various plastic materials.

The distribution pipe 420 may be a pipe connected to the supply pipe 410, spaced apart from each other along the one direction, and extending in a direction transverse to the one direction (see FIGS. 3 and 4). The distribution pipe 420 may distribute water supplied through the supply pipe 410 to a plurality of spray nozzles 430 to be described later. The distribution pipe 420 may have the same diameter to distribute an equal amount of water to the plurality of spray nozzles 430 .

The distribution pipe 420 may vary in number and diameter depending on the amount of water required and the spraying range of the water. For example, when the spray nozzle 430 to be described below is a spray spray method, water is sprayed while spreading widely from side to side, and thus a small number of distribution pipes 420 may be required. On the other hand, when fine water droplets flow in the gravitational direction through a hole (not shown), the water moves only in a direction perpendicular to the ground, so a large number of A distribution pipe 420 may be required.

The spray nozzle 430 is coupled to the supply pipe 410 and is disposed at regular intervals along the one direction to spray water. The spray nozzle 430 may be positioned above the front surface of the porous tile 100 to spray water toward the front surface of the porous tile 100 . A spray hole (not shown) of the spray nozzle 430 may be formed to evenly spray water like a spray or flow fine water droplets in a direction of gravity.

For example, the interval between spray holes (not shown) may be 200 mm or less. When the interval between the spray holes exceeds 200 mm, it may be difficult to evenly spray water on the entire surface of the porous tile 100 . However, the number and spacing of the spray nozzles 430 are not necessarily limited thereto, and the number and spacing of the spray nozzles 430 may be changed as needed.

The water drainage unit 500 may include a drainage pipe 510, an auxiliary pipe 520, a drainage hole 530, a barrier 540, and a drainage passage 550 (see FIG. 5). The water drainage unit 500 is connected to the water storage unit 200 and is located at the lower end of the porous tile 100 to collect and drain water moving downward by gravity. Here, those of ordinary skill in the art related to this embodiment will understand that other general-purpose components in addition to the components shown in FIGS. 1 to 6 may be further included in the water drainage unit 500. can

The drain pipe 510 may be a pipe connected to the water storage unit 200 and extending in one direction from the bottom of the porous tile 100 . The drain pipe 510 may serve as a passage for moving collected water to the water storage unit 200 . The length and shape of the drainage pipe 510 may vary depending on the amount of water to be drained and the arrangement and width of the porous tile 100 .

The auxiliary pipe 520 may be a pipe connected to the drain pipe 510, spaced apart from each other along the one direction at regular intervals, and extending in a direction transverse to the one direction. The auxiliary pipe 520 may be connected to a drain hole 530 to be described later and may be a passage through which water drained through the drain hole 530 moves to the drain pipe 510 .

The drain hole 530 may be a hole for drainage connected to the drain pipe 510 and located at a lower end of the porous tile 100 . The drain hole 530 prevents the water supplied from the water supply unit 400 from evaporating and moving in the direction of gravity through the porous tile 100 (see FIG. 6) to prevent pooling at the lower end of the porous tile 100. . At least one drainage hole 530 may be disposed at regular intervals to prevent water from pooling in a specific area. The diameter of the drainage hole 530 may be changed according to the amount of water to be drained.

The barrier 540 may be a barrier rib disposed at a predetermined distance from the front surface of the porous tile 100 . The prevention wall 540 may prevent water supplied to the porous tile 100 from moving in the direction of gravity and flowing to the floor, not the humidifier 10, before being drained through the drain hole 530.

The drain passage 550 is formed as a U-shaped valley, and water may flow before being drained into the drain hole 530 . The drain hole 530 described above is located at the lower end of the drain passage 550 so that water accumulated in the drain passage 550 can be drained through the drain hole 530 .

The control unit 600 is coupled to the water supply unit 400 to adjust the amount of water sprayed by the spray nozzle 430 . The control unit 600 may be coupled to the water storage unit 200 and control the power of the motor 220 to control the amount of water supplied to the water supply unit 400 .

The control unit 600 may control the supply amount of water using temperature and humidity transmitted from the first sensor 710 and the second sensor 720 of the sensor unit 700 to be described later. The controller 600 compares and analyzes the temperature and humidity data of the porous tile 100 measured by the first sensor 710 and the temperature and humidity data of the surrounding environment measured by the second sensor 720 to maintain proper humidity. The amount of water supplied can be controlled. The controller 600 is configured as described above to automatically adjust the water supply cycle according to ambient humidity. Although the sensor unit 700 in this embodiment is described as being composed of the first sensor 710 and the second sensor 720, it is not necessarily limited thereto, and the location, number, etc. of the sensor unit 700 may vary. there is. For example, it is described that the sensor unit 700 is located adjacent to the porous tile 100, but is not limited thereto, and the sensor unit 700 is located in an operation switch spaced apart from the porous tile 100 so that the porous tile ( 100) may measure temperature or humidity at a location away from it.

The sensor unit 700 may include a first sensor 710 and a second sensor 720 . The sensor unit 700 may measure the ambient environment and the temperature and humidity of the porous tile. The sensor unit 700 may be any type of sensor capable of measuring temperature and humidity.

[Humidifying performance of porous tiles]

Porous tiles having an average porosity of 5 μm or less and a porosity of 30% (Co., Ltd. LXhausis "Sumtile") 18 sheets (1.62m ² ) using a water supply device to the pores of the porous tile (100) After being saturated with water, it was placed in an enclosed space (55.65 m ² ) with a relative humidity of 31.4% without overlapping, and the change in temperature and relative humidity per hour was measured. indicated respectively.

7 is a graph showing changes in temperature and relative humidity over time in the bedroom space when the porous tile of FIG. 1 is immersed in water and then placed in the bedroom space, and FIG. 8 is a graph showing the porous tile of FIG. 1 immersed in water This is a graph showing the change in absolute water vapor content in the bedroom space when it is placed in the bedroom space after

7 and 8, after 1 hour, the relative humidity was 40.6%, so it was possible to achieve a relative humidity of 40% or more within 1 hour, and after 16 hours, a relative humidity of 57.7% was achieved, resulting in high humidity. was kept on At this time, the net amount of water vapor introduced into the space for 1 hour was 82.3 g/h, and the humidification contribution per porous tile 100 was measured to be 4.6 g/h.

As the above results, the porous tile 100 according to the present invention exhibits an excellent humidification effect in a short time without noise problems and additional work, and maintains the humidification effect for a long time.

[Water Absorption Performance of Porous Tiles]

Water was passed through the porous tile 100 and water absorption over time was measured. The amount of water shed is shown in Table 1, and the water absorption of the porous tile 100 is shown in Table 2 and FIG.

time (min) One 2 3 4 5 spilled water (g) 150 298 427 552 681

time (min) Absorption rate (%) Absorption (g) One 12.3 117 2 19.9 190 3 24.8 238 4 25.7 246 5 26.0 249

9 is a graph showing the water absorption rate of the porous tile over time when water is applied to the porous tile of FIG. 1 .

Referring to Tables 1, 2, and 9, 117 g of 150 g of water flowed through the porous tile 100 was absorbed after 1 minute, and the water absorption rate of the porous tile 100 reached 12.3%. After 2 minutes, 190 g of 298 g of water flowed through the porous tile 100 was absorbed, and the water absorption rate of the porous tile 100 reached 19.9%.

As such, it can be confirmed that the porous tile 100 according to the present invention has a large specific surface area and a large pore area, and absorbs water at a high speed and reaches a high absorption rate. Accordingly, it takes a short time to absorb water into the porous tile 100, and it is possible to prevent unnecessary water supply by reducing the amount of water that falls without being absorbed.

[Water absorption performance according to the location of the porous tile]

The porous tile 100 is composed of a temporary wall composed of four layers in the direction of gravity (see FIG. 11), and water is flowed from the top of the porous tile 100 for 10 minutes. After 10 minutes, the water absorption of each porous tile 100 was measured. . The uppermost porous tile 100 is at the first location, the porous tile 100 at the bottom of the first location is at the second location, the porous tile 100 at the bottom of the second location is at the third location, the porous tile at the bottom of the third location The water absorption according to the position of the porous tile 100 when (100) is the fourth position is shown in FIG. 10 . At this time, the time for the water to pass to the porous tile 100 below is shown in FIG. 11 .

10 is a graph showing water absorption according to the location of the porous tile of FIG. 1 , and FIG. 11 is a diagram showing the time required for water to arrive depending on the location when water flows on the porous tile of FIG. 1 .

10 and 11, after 10 minutes, the porous tile 100 in the first position had a water absorption of 26.2%, the porous tile 100 in the second position had a water absorption of 24.9%, and the porous tile 100 in the third position had a water absorption rate of 26.2%. 22.4%, it can be seen that the porous tile 100 in the fourth position reaches 12%.

In addition, after 2 minutes, water starts to pass to the porous tile 100 in the second position, 4 minutes and 30 seconds in the porous tile 100 in the third position, and 7 minutes and 30 seconds in the porous tile 100 in the fourth position. After a few seconds, the water started flowing. It can be seen that as the position of the porous tile 100 goes downward, the time interval at which water passes to the next tile increases.

As such, it can be seen that the water absorption rate of the porous tile 100 of three layers from the top reaches 22% for a short time of about 10 minutes, and thus sufficiently absorbs water. In addition, it can be seen that the amount of water that is not absorbed into the porous tile 100 and flows down to the floor and is discarded can be minimized, since the time interval for water to flow to the next tile becomes longer as it goes downward.

[Moisture-proof performance according to moisture content of porous tile and change in moisture content over time]

Moisture-proof performance over time was measured by varying the moisture content of the porous tile 100, and the results are shown in FIG. 12 . In addition, the change in moisture content over time is shown in FIG. 13 .

12 is a graph showing the amount of moisture per sheet according to the moisture content of the porous tile of FIG. 1 , and FIG. 13 is a graph showing the change in moisture content of the porous tile of FIG. 1 according to drying time.

Referring to FIG. 12, in the humidification device 10 using porous tiles, the higher the moisture content of the entire porous tile 100, the higher the amount of moisture released per porous tile 100, and when the moisture content is 20% or more, similar It can be seen that it exhibits a level of moisture-proof performance.

In addition, it can be confirmed that the moisture release amount is the largest for 1 hour after absorbing water, and the moisture release amount is uniform after 2 hours.

Referring to FIG. 13 , it can be seen that the higher the initial moisture content, the greater the moisture-proofing effect and the longer-lasting moisture-proofing efficiency.

Therefore, it can be seen that in order to increase the moisture-proofing performance of the humidifying device 10 using the porous tile, it is appropriate to initially absorb a large amount of water into the porous tile 100 to maintain high moisture-proofing efficiency for a long time. As described above, when water is supplied to the upper part of the porous tile 100 composed of four layers, a lot of water is absorbed in a short time, so it can be seen that high moisture-proof efficiency can be maintained for a long time.

Hereinafter, a humidifying device 10 using a porous tile according to a second embodiment of the present invention will be described.

14 is a perspective view illustrating a water supply unit of a humidifying device using a porous tile according to a second embodiment of the present invention.

Referring to FIG. 14, the humidifying device 10 using a porous tile according to the second embodiment is the same as the humidifying device 10 using a porous tile according to the first embodiment, except for the water supply unit 400. Since it has the same structure as, redundant description of the same structure will be omitted.

According to this embodiment, the water supply unit 400 may include a supply groove 440 .

The supply groove 440 is a groove that is connected to the water storage unit 200 and extends in one direction on the top of the porous tile 100 and can temporarily contain water. Water accommodated in the supply groove 440 may overflow the supply groove 440 and flow down along the porous tile 100 in the direction of gravity.

When water is supplied in this way, high moisture-proofing efficiency can be maintained for a long time by supplying water evenly to the porous tile 100 at a high speed.

In the above, one embodiment of the present invention has been described, but those skilled in the art can add, change, delete, or add components within the scope not departing from the spirit of the present invention described in the claims. The present invention can be variously modified and changed by the like, and this will also be said to be included within the scope of the present invention.
